MACHINE FOR WASHING EDIBLE ANIMAL TISSUES.

Application filed December 27, 1920. Serial No. 433,086.

To all whom it may concern:

Be it known that I, HENRY B. BUoKHAM, a citizen of the.United States, residing in Chicago, in the county of Cook and State of Illinois, have invented, a new and useful Improvement in Machines for Washin Edible Animal Tissues, of which the following is a specification.

This invention relates to a machine for washing edible animal tissues and has for an object the provision of a machine of this nature that is simple and economical in construction, efiicient in operation, and that affords a quick and ready discharge of the .tissues which have undergone a washing treatment in the machine.

' In addition to the general objects recited above, the invention has for further objects such other improvements or advantages in construction and operation as are found to obtain in the structures and devices herein"- after described or claimed.

In the accompanying drawings forming a part of this specification, and showing, a preferred form and manner in which the invention may be'embodied and practiced,

, but without limiting the claimed invention specifically to such illustrative instance or.

instances: a

Figure 1 is a sectional elevation of a washing machine constructed in accordance with the present improvements;

Figure 2 is an end view thereof looking from the left hand end of Figure 1;

Figure 3 is an end view looking from the right hand end of Figure 1;

Figure 4 is a transverse vertical-section of the machine;

F igure5 is a view similar to Figure 4 showing the parts in position for dumping the treated tissues.

The same characters of reference indicate the same parts in each of the several views of the drawings.

The machine of the present invention is especially constructed for washing edible animal tissues, such as sweetbreads and the like, and for convenience the present description will be confined to this use of the invention. Features of construction and op-- eration are, however, adaptable to other valuable applications; consequently, the scope of the invention is not confined to the specific use and specific embodiment herein described as an illustrative example.-

Referring to the drawings, the machine g embodies in its construction a substantially cylindrical casing 11 supported at its opposite ends by means of pedestals 12 and 13. A section 14-of the casing wall is hinged at 15 to the mainbody of the casing, so as to provide a hinged cover which may be opened to deposit the material to be treated into the interior of the casing and closed during the periodof the treatment of the material. The opposite end plates 16 of the casing 11 are provided with bearings 17 which respectively support stub shafts 18 projecting from the opposite end plates 19 of a drum 20 revolubly mounted within the casing 11. The left hand stub shaft 18 of the drum 20, as viewed in Figure 1, projects through the bearing 17 and is provided at its outer end with a large driven gear 21. This gear 21 is enmeshe'd with a small driving gear 22 on a parallel driving shaft 23, the latter receivingits' power from pulley connections 24 of any preferred type.

As shown, the drum 11 is of substantially cylindrical form, being constituted of a foraminous or perforate cylindrical wall having a hollow interior Within which are deposited the animal tissues to be treated.

Secured to the interior of the drum l1 and extending in a direction parallel with its axis are blades or scrapers 36. These blades or scrapers are located at convenient distances around the interior of the drum and project inwardly therefrom, so that they act to carry the material being treated around the inner surface of the drum, so

. as to expose all parts of the material to the cleansing action and efi'ect a thorough agitation of the material during the washing operation. In order to permit ready and convenient charging of the drum with the material, as well as discharging of the treated material from the drum, as will hereinafter appear, a portion ofthe perforate cylindrical wall of the drum is formed of removable sections 25. One longitudinal edge of the main body portion of the drunr interior of the casin is formed with a plurality of spaced pairs of lugs 26 having aligned holes 27. The lateral arcuate edges 28 of the removable sections 25 are respectively constituted of bands projected beyond the outer faces of the removable sections, as shown in Figure 4,, and also extending beyond the upper longitudinal edges 29 of the removable sections. The so extended portions of the bands 28 are cut into the form of pairs of lugs 30 that are respectively adapted to receive a lug 26 of the main body portion of the drum. The lugs 30 are formed with holes adapted to align the holes 27. of the lugs 26, when the removable sections 25 are positioned to close the drum. As shown in Figure 4:, the ends of the bands 28, opposite to the lugs 30, are inturned to rest upon the bottom contiguous edge of the main portion of the drum and to lockbehind said edge when the removable sections 25 are positioned on the drum.

When the removable sections 25 are positioned on the drum, pins 31 are inserted through the alignedholes of the interlocked ears 26 and 30 to retain the removable sections in position with respect to the main.

xtending along in front of the casing 11 and just below the bottom edge of the hinged cover 14 is an inclined trough 32 connected at its discharge end with a discharge pipe 33. Wash water and other matterspilled out of the drum may discharge through the trough 32 and "be carried away by the pipe 33. Formed it the bottom of the casing 11 is an inclined. discharge trough 34: for the material. The upper end of said trough 34 is.

provided with pipes 35' through which a suply of steam and water is introduced into the during the treatment of the material, an .the lower end of the trough is provided with a manually operable gate 36 which may be opened when discharging the .treated. material and closed during the treatment of the material. The wash water discharges through a pipe 37 leading from the trough at a point near its lower end.

I n operating the machine, the casing is' opened by. swinging up the cover14 and the drum is then rotated so that the removable sections thereof are in position behind the open portion of the casing. The sections are then removed, and the tissue to be treated is deposited in the drum. The removable sectionsof the drum are then re-applied, the cover of the casing is closed and'the steam is turned'on into the steam suppl pi s .35., The drum is then rotated for t e esired period of time to thoroughly cleanse the material and when the cleansing operation has been completed, the rotation of the drum is stopped, the cover 14 is again opened, and

-the removable sections '25 of the drum are againremoved. When this has been accomdischarge the washe iaaaeae plished, the drum is rotated so thatthe 01'- trough v34. The washed tissue then discharges into the trough 34; and may, by the appllcation of wash Water through the pipes 35, be washed out through the gate 36. v

,The invention as hereinabove set forth is embodied in a particular form of construction, but may be variously embodied wlthin the scope of the claims hereinafter made.
